One aspect of the present invention relates to a method of preparing radiofluorinated substituted alkyl, cycloalkyl, aryl, and alkenyl compounds. In a preferred embodiment, potassium fluoride-18 is used. Another aspect of the invention relates to piperazine compounds containing fluorine-18 that are useful as imaging agents. In certain embodiments, the piperazine compounds contain a quaternary amine. Another aspect of the invention relates to arylphosphonium compounds containing fluorine-18 that are useful as imaging agents. In certain embodiments, the phosphonium compound is a tetraaryl phosphonium salt. Another aspect of the present invention relates to a method of obtaining a positron emission image of a mammal, comprising the steps of administering to a mammal a compound of the invention, and acquiring a positron emission spectrum of the mammal.
本发明的一个方面涉及制备放射性氟代取代烷基、环烷基、芳基和烯基化合物的方法。在一个优选实施例中,使用氟化钾-18。本发明的另一个方面涉及含氟-18的哌嗪化合物,其作为成像剂有用。在某些实施例中,哌嗪化合物含有季铵胺基。本发明的另一个方面涉及含氟-18的芳基膦盐化合物,其作为成像剂有用。在某些实施例中,磷膦化合物是四芳基膦盐。本发明的另一个方面涉及一种获得哺乳动物正电子发射图像的方法,包括以下步骤:向哺乳动物注射本发明的化合物,并获取哺乳动物的正电子发射光谱。
